“Unidentified developer” error message on Mac

You get this message when launching the installer or application for a FontLab app such as FontLab VI or FontLab Studio 5: "[name of application]  can't be opened because it is from an unidentified developer. Your security preferences allow installation of only apps from the mac App store and identified developers."


You are being stopped by the macOS “Gatekeeper” feature. The app is not “signed,” and GateKeeper does not like this.
You have to get around the security of GateKeeper the first time you run a given version of the app.

To get around the alert message:

  1. Find the original app, usually in your Applications folder (not the icon in your dock, if you have put one there).
  2. Right-click (or Ctrl-click) on the application icon and choose “Open”. 
  3. Then click on the “Open” button at the warning dialog, to launch the app anyway.
  4. This will allow FontLab to continue launching until the next time you update it to a new version.

Note: you can permanently disable this type of warning, but we do not recommend it.
